SPINNING-RING.

SPECIFICATION forming part of Letters Patent N 0. 536,566, dated March26, 1895.

Application filed August 24, 1893. Serial No. 483,890. (No model. I

To aZZ whom it may concern.-

Beit known that 1, JAMES FOWLER, of Pawtucket, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvementsin Spinning-Rings; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention has reference to improvements in spinning-rings. i

The object of the inventi s to so construct a spinning-ring that by theuse of trav: elers an automatically varying tension may be exerted onthe yarnsjoeing spun.

The invention consists in the peculiar construction of the spinning ringarrahf gd to provide independent flanges on which winding andtensRmQaveler-s may move.

The invention a so-consists in the peculiar combination of the flangeswith each other and the use of two independent travelers.

Theinvention further consists in such other peculiar features ofconstruction and combination of parts as will hereinafter be more fullydescribed and pointed out in the claims.

Figure 1 represents a plan view of the improved spinning-ring with thewinding and tension travelers on their'respective flanges. Fig. 2represents an elevation of the same. Fig. 3 represents a verticalsectional view of the ring to more clearly show the constructionthereof.

Similar numbers of reference designate corresponding parts throughout.

Yarn, to be perfect, must have a uniform twist and tension from theempty to the full bobbin. This has not heretofore been practicable witha single traveler serving as a constant factorin winding and twisting,while the power and peripheral speed of the bobbin is subject toconstant variation during the winding of the yarn thereon. In theordinary single spinning-ring it is found that the tension exerted bythe traveler on the yarn does not prevent the ballooning of the yarnbetween the traveler and the pig-tail thus requiring the use ofseparators to prevent the yarn being woundvon'one bobbin from inter 5ofering with that which is being wound on to the bobbins carried by theadjoining spindles. When ring-rails are warped, or the rings are out oftrue, an unequal twist is given to the yarn by the varying movement ofthe travclear and the rings and travelers are subjected foundue wearwhile the breakage of the yarn is considerable.

In carrying my invention into effect it has been my object to overcomethe abovennen the outer or tension ring having an inclined 7otraveler-flange 1O concentric with the flange of the inner ring andfurnished with outer and inner race-ways for the ends of the traveler, avertical, circular wall 11 supporting the flange 10, and aninwardly-turned bottom flange 12 the circular opening in which closelyembraces the sleeve 5 of the inner ring and bears against the shoulder6. Through the wall 11 are cut ports 1313 through which lint or dust maybe removed, and surround- 8o ing the sleeve 5, below the bottom flange12, is a collar 14 adapted to support this botto'm flange with its wall11 and flange 10. On the inner flange 7 is carried a traveler 15 of theusual construction, but generally very light, and on the outer flange 10is carried the tension traveler 16 the weight of which is determined bythe size of yarn to be spun as well as by the diameter of the emptybobbin to be used.

It is obvious that the cohstruction of the rings may vary considerablyfrom that shown in the drawings. They may be constructed from one pieceof metal or may be secured together in a different manner, while the 5flanges 7 and 10 may have any desired crosssectional shape or may beinclined more or less from the horizontal. If found to be desirable theflange 10 may extend in a vertical plane, or may be located above orbelow the [O0 flange 7, the object being broadly to provide twoindependent; traveler flanges; for each spindle, on which travelers maymove independently of each other.

In threading,the yarn is first passed through the traveler 16, thenthrough the traveler andis then carried to the bobbin. Atthecommencement of the spinning the two travelers, will, under normalconditions, travel at about the same rate of speed. Should the yarn,however, be delivered faster than it is being spun it is evident thatthe tension traveler 16 will fall back and take up the slack, while,when the diameter of the bobbin becomes enlarged by the winding thereonof the yarn, a tension will be automatically created by the drag of thetension-traveler which will tend to reduce the speed of the windertraveler. Where the rings are not exactly concentric to the spindle thetension traveler will take up the surplus yarn on the short side ofthe-ring nearest to the spindle and will allow it to be drawn out on theside farthest from the spindle. The tension traveler will also takeupthe surplus yarn between the winder traveler and the rolls preventingthis yarn from lapping around the rolls and being broken, or fromballooning.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. Inaspinning-ring, the combination with an inner annular traveler-flange,and a winder-traveler movable on said flange,of an outer flangeembracing and connected to the inner flange, and a tension-travelermovable on said outer flange.

2. In a spinning-ring, the combination with an inner traveler-flangehaving a securing sleeve, and a traveler movable on said-flange, of anouter traveler-flange mounted on said securing-sleeve and a travelermovable on said outer flange.

3. The combination with an inner spinningring having, a securing-sleeve5 a travelerflange 7, and the traveler 15 movable on said flange7 of anouter ring having the travelerflange 10, the wall 11 provided with portsl3=-13, the bottom flange 12 secured to the sleeve 5, and a tensiontraveler movable on the flange 10, as and for the purpose described.

In witness whereof I have hereunto set my hand.
